WhatsApp beta has picked up an update to 2.16.272 that lets users tag people in group chats. To tag someone in a chat, just use the @ symbol and start typing out the contact's name. You'll see suggestions pop up as you start typing, and you can even tag multiple contacts in the same message if you like annoying several people at once. Even if the intended contact has that particular group chat muted, he or she will receive the notification once you tag them.
If you're like me and are enrolled in several WhatsApp groups that you have no intention of being in, the new update makes it harder to ignore conversations that have no bearing on your life. I'm sure there are individuals having meaningful conversations on WhatsApp. I just have trouble believing that they belong to this dimension.
Today's "feature" should be making its way to the stable client in the coming weeks. Enjoy the solace while it lasts, folks.
